    Yes they are rpm's but: the header (*.hdr) files and many RPM (*rpm)
    files can be compressed to save space and bandwidth.

    There are some "httpd" (apache) web server tricks involving
    compression that may come to play here. I just did a quick look at
    the compression ratios on *.hdr files and see some interesting
    numbers.

    For headers the worst were
        46.5% 47.4% 47.6% 47.8% 47.9% 48.0%
    and the best were
        74.6% 74.7% 74.8% 75.4% 76.1% 78.9%
    I saw two ringers at 84% and 95% that I do not believe and want to check.

    As for the rpm update packages I see compression ratios
    that run from the expected:
       -0.0% 0.0% 0.0% 0.0% 0.0% 0.1% 0.1% 0.1% 0.1% 0.1% 0.1%
    to the unexpected:
       34.4% 43.3% 44.5% 45.2% 45.9% 46.7% 48.2% 58.7% 59.1%
    This tells me that a responsible archiving web site manager would be
    using all the compression tricks at his or her disposal to our
    advantage.

    Read more about it:
